Sorry but I really prefer not to answer the A vs B camera questions. If they're on my "Best Cameras" list then they're good ones. Each one has it own merits whether it be size or unique features (image stabilization) and you have to make up your own mind based on the camera's ergonomics, size, price and image quality. Look at our review and sample images and visit the other digicam web sites and read their reviews too. The more information you have the better.
